2019獨(dú)角獸企業(yè)重金招聘Python工程師標(biāo)準(zhǔn)>>>

使用Jfinal一段時(shí)間了,記得當(dāng)初14年吧,為了建立一個(gè)簡單的門戶網(wǎng)站,想找個(gè)輕量型的急速開發(fā)框架,然后搜到Jfinal,然后用了一段時(shí)間后,確實(shí)不錯(cuò), 現(xiàn)在吧,隨著時(shí)間的推移,作者對JFinal的版本迭代也是一直在努力,一直朝著優(yōu)秀的方向走去;

這里做下對Jfinal的使用記錄;

為什么要用Jfinal:?

• 輕: 輕到什么程度呢, 體積小,框架僅339K，且無第三方依賴
• 快
  • 開發(fā)快:?粘貼復(fù)制就是可以做到簡單的模塊增刪改查;
  • 啟動(dòng)快: 內(nèi)置jetty啟動(dòng),直接運(yùn)行main方法就可以啟動(dòng)整個(gè)web項(xiàng)目
  • 編譯快: 熱編譯的支持,更是讓jfianl使用者留下更多的時(shí)間陪家人
• 便捷
  • 支持Validator后端校驗(yàn)
  • AOP支持,攔截器配置靈活便捷
  • Plugin體系結(jié)構(gòu),擴(kuò)展性強(qiáng),比如兼容spring定時(shí)器什么的也可以做到(當(dāng)然,不推薦使用xml的方式)
  • 無xml配置,框架接口簡單明了
• 學(xué)習(xí)成本低,上手快,,這才是重點(diǎn);節(jié)約更多的時(shí)間可以去陪戀人,家人

說了Jfinal的好處,那么Jfinal到底適合哪些應(yīng)用場景呢,適合多大的運(yùn)行項(xiàng)目呢;

適合中小型項(xiàng)目,這主要是針對一些業(yè)務(wù)處理不是很復(fù)雜的項(xiàng)目;

• ???????看表?? ? 200來張表 ,可以定位中型項(xiàng)目吧
• ????????? ? ? 看代碼量 ? ?(未知)
• ???????????????? ? ? 物理大小 ? (未知)

? ???????看案例吧,具體說也難說, 看到的才最明了,?以下是Jfinal做的一些項(xiàng)目:

相對于 struts2 性能提升 8 倍左右，相對 spring 性能提升兩倍多,只要服務(wù)器性能好并且沒有數(shù)據(jù)庫或其它瓶頸，并發(fā) 1000 以上不是問題;

不過,Jfinal只不過是你整個(gè)架構(gòu)的一部分,并發(fā)訪問量承受能力完全取決于你的整體架構(gòu)如何;

官方并沒有給出具體數(shù)據(jù),以上數(shù)據(jù)類型是截至開源社區(qū)中的內(nèi)容;?

沒有對比就沒有傷害(Jfinal PK springMVC)

• 開發(fā)效率至少比spring快三倍以上(主要由于熱編譯,啟動(dòng)快,結(jié)構(gòu)簡單,無xml)
• Jfinal?Db + Record模式，靈活便利 ,維護(hù)量少
• spring 本身就很厚重，在加上ser/get封裝類,維護(hù)麻煩
• 同樣是添加Validator后端校驗(yàn),springMVC配置則要麻煩的多?
• 更多的就需要你自己去體驗(yàn)了

以上對比是在開發(fā)中小型(業(yè)務(wù)不復(fù)雜)項(xiàng)目的時(shí)實(shí)際經(jīng)驗(yàn)總結(jié); ?
